Elastic unit is developed by our elastic unit workshop. We possessed the professional production line and advanced technology assembly and inspection equipment, a engineer team with wide experienced technicians, a advanced management system, the elastic sensitive unite is famous for adopting various material, reasonable design, excellent processing, good quality. Our institute adopted the aviation technology to develop the civil product, we have the elastic sensitive unite: metallic spring elements, diaphragm, pressure (or vacuum) capsule, metal welding bellow, mechanical seal , wave washer, "O" sealing ring (including "C" sealing ring), vapor steam trap, various floating ball, etc. Meanwhile, According to different requirements from customers, adopt correct process to manufacture product with materials as beryllium copper, austenite stainless steel, elastic alloy, precipitation harden stainless steel, etc. the elastic sensitive unite have high sensitively, long-serve life, high temperature, high resistant pressure density and used in wide applicable range, can be used as key measuring components, seal components, compensating components, and supply various kinds of pressure measurement sensor.
